Lifecycle Timeline
5DescriptionCVE.org
Software installed and run as a non-privileged user may conduct improper GPU system calls to force GPU to write to arbitrary physical memory pages.
Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform altering their behaviour.
This attack can lead the GPU to perform write operations on restricted internal GPU buffers that can lead to a second order affect of corrupted arbitrary physical memory.
AnalysisAI
Local privilege escalation in Imagination Technologies Graphics DDK allows low-privileged users to corrupt kernel memory and driver data structures through malicious GPU system calls. The vulnerability affects DDK versions 1.18 RTM, 23.2 RTM, 24.1-24.2 RTM, and 25.1-25.3 RTM. …

Vulnerability AssessmentAI
| Exploitation | Attacker must have local authenticated access to the system with low-privilege user account (PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is HIGH for multi-user systems and moderate for single-user workstations. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a standard user account on a shared Linux workstation running vulnerable Graphics DDK 25.2 RTM opens a legitimate GPU-accelerated application or creates a minimal program that requests GPU resources. The malicious code issues crafted GPU system calls through the driver interface, embedding commands that direct the GPU DMA engine to write attacker-controlled data to kernel memory pages outside the GPU's allocated buffer pool. … |
| Remediation | Apply vendor-released patches from Imagination Technologies immediately, prioritizing systems with multiple local users or untrusted workloads. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all systems running Imagination Technologies Graphics DDK and identify affected versions (1.18 RTM, 23.2 RTM, 24.1-24.2 RTM, 25.1-25.3 RTM). …
